Foxboro FCP70 I/A Series Field Control Processor

Description

Function Features

• Comprehensive Control Capabilities

  It integrates regulatory control, logic control, and sequential control functions. It supports common industrial control algorithms such as proportional-integral-derivative, ratio control, and cascade control, and can also execute custom logic operations. It can handle both continuous process control such as chemical reaction temperature regulation and discrete control such as assembly line sequential actions, adapting to diverse industrial control scenarios.

• Reliable Fault Handling and Alarm

  It is equipped with a complete self-diagnostic function that continuously detects its own circuit, communication link, and connected fieldbus module status. When a fault occurs, it immediately triggers an alarm and sends detailed fault information to the upper-level system. It records fault logs including occurrence time and fault type to assist maintenance personnel in quickly locating and troubleshooting problems. In addition, it supports fault-tolerant configuration with dual modules, and the standby module can immediately take over work when the main module fails to avoid production interruptions.

• Convenient On-site Maintenance and Upgrade

  It supports online program updates and configuration modifications. Operators can adjust control parameters and modify control logic through the upper-level system without shutting down the production process, reducing the impact of system adjustments on production. The modular structure allows hot-swapping, enabling quick replacement of faulty modules and shortening maintenance downtime.

• Stable Data Interaction and Synchronization

  It realizes high-speed data transmission with the upper-level control network, ensuring timely upload of on-site process data and rapid issuance of control commands. It supports time synchronization with the system clock, ensuring that the time stamps of data collected from different field devices are consistent, which is crucial for analyzing the correlation of process parameters and tracing production events.

Application Scenarios

• Oil and Gas Industry

  It is deployed in oil drilling platforms and oil refineries. It connects with pressure and flow fieldbus modules on-site to monitor the pressure of oil and gas pipelines and the flow of crude oil during extraction in real time. It controls the opening of regulating valves and the speed of pumping equipment through preset logic, ensuring stable oil and gas extraction and transportation. The fault-tolerant design ensures continuous operation of the control system even in harsh marine or desert environments, preventing safety accidents caused by sudden loss of control.

• Thermal Power Industry

  It is applied in the boiler and steam turbine control systems of thermal power plants. It collects data such as boiler flue gas temperature, steam pressure, and turbine speed through field sensors and fieldbus modules. It adjusts the coal feeding amount and air supply volume of the boiler and the opening of the steam valve of the turbine to maintain the generator set operating at the rated power. Its fast algorithm execution speed ensures rapid response to load changes of the power grid and improves the stability of power supply.

• Chemical Industry

  It is integrated into chemical production lines involving reaction kettles, distillation columns, and other key equipment. It monitors key parameters such as temperature, pressure, and material concentration in the reaction process. It precisely controls the feeding speed of raw materials and the discharge flow of products to ensure that chemical reactions proceed within the set parameters. For example, in the ethylene production process, it maintains the temperature of the cracking furnace within the optimal range, improving product yield and quality.

• Water and Wastewater Treatment Industry

  It is used in urban sewage treatment plants and industrial wastewater purification systems. It connects with water quality sensors, flow meters, and other field devices to collect parameters such as pH value, turbidity, and dissolved oxygen in water. It controls the operation of dosing pumps, aerators, and filter equipment, adjusting the dosage of chemicals and aeration intensity according to water quality changes. This ensures that the treated water meets the discharge or reuse standards and improves the efficiency of water treatment.

• Food and Beverage Industry

  It is deployed in large-scale food processing and beverage production lines, such as milk pasteurization lines and beverage filling lines. It controls the pasteurization temperature and time to ensure the elimination of harmful bacteria while retaining the nutritional components of food. In the filling process, it adjusts the filling speed and amount to ensure uniform filling volume of each product. Its stable and accurate control capabilities meet the strict quality requirements of the food and beverage industry for production processes.
